Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691964, here are decompositions:

3 + 8691961 = 8691964
23 + 8691941 = 8691964
41 + 8691923 = 8691964
131 + 8691833 = 8691964
137 + 8691827 = 8691964
233 + 8691731 = 8691964
311 + 8691653 = 8691964
383 + 8691581 = 8691964

Showing the first eight; more decompositions exist.
